Best route for vent pipe?

I need to bring the vent for this kitchen sink to the right of this window. All my vents are 2, but I could reduce down this portion to pass through the 2x4 studs or there is a 8 metal purlin directly behind the 4 studs on the right that I may be able to drill through. Should I drill/notch all the studs or try going through the purlin? Any suggestions?
code is IPC.

You can downsize to 1.5" vent for the kitchen sink. That'll help a bit with notching. And getting it as much behind the triple stud would be best. It looks like you have probably close to 1.5", so might only need to notch 3/4" or so - which would be much better than a 1.75" hole!

I'd also recommend a stud shoe. Something like this (no idea about this vendor, it was just the first that popped up)
